RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Screenshot of the issue

Filed from caserun (https://tcms.engineering.redhat.com/run/265069/#caserun_11178678)

Version-Release number of selected component (if applicable):
6.7.z
firefox-38.4.0-1.el6_7.ppc64
firefox-38.4.0-1.el6_7.ppc

Steps to Reproduce: 
1. Open Firefox


1. Click the menu button.

2. Select "Customize" at the bottom left of the menu.

3. Click and drag "Developer" from the menu to the "Additional Tools and
Features" area directly to the left.

4. Select "Exit Customize"

5. Open the Menu.



Actual results: 
Customize page never loads, blank forever.
Firefox crashed upon close the first time this was tested but no crash when reproduced.

Expected results:
"Developer" has been removed from the menu.

We're not going to fix that for PPC only.
